In addition to common payment gateway features including recurring
billing, refunds and fraud management, PayPal Express Checkout is
specifically designed to drastically reduce occurrences of cart
abandonment. How? By giving your buyers all of the essential
transaction information at once including an order outline,
shipping options and tax details.
